Well, I have to choose
Jasper. I've loved
Jasper a long, long time; it's a family name for me and on top of that, and it's a rather intriguing stone connected to memories of rock-hounding with my grandpa. I like
Jethro and I'm rooting for him but he can't beat out
Jasper with me, especially not with that well-known bumbling, empty-headed association in his back pocket.
I imagine I've probably just nudged you further toward
Jethro. :)
